I just see a tech features of the scope and 3 links for manual, datasheet and demo request.
No firmware or download link.

Pro tip: Try the "Software & Firmware" section. Scroll down until you get to the light-grey background, then there's a menu bar (tab selector).

Maybe an issue with my source or cable, odd it doesn't show up when on single channel though. Will try again later with a proper source.

The problem is trying to trigger at 2ns/div horizontal when you have 1GS/sec sample rate.

Yeah, though even if I drop the source signal frequency by half to compensate for 1GS/s vs 2GS/s, signal is still not clean. As explained above there are probably higher frequency components causing issues, so I need to find a cleaner sine source more suitable for testing.

Additional hardware filtering options would be useful, the MSO5000 had 100MHz and 200MHz filters. In this case we know at least a 100MHz filter could be implemented (since the ~100MHz bandwidth option exists).

edit: maybe some filter is applied with 2ch on, since 3dB is dropping ~80MHz? But it seems not ideal.

Indeed, an additional 100MHz option as filter can be useful.
But we can send SCPI commands to switch between 70/100/200MHZ.
Antonio90:
I'm wondering how hard would it be to do FFT with Matlab's signal processing suite, extracting the waveform data form the scope.
Maybe even bode plot with the instrument control and/or audio apps?
Could someone extract some kind of waveform from his scope and post it? I don't have a scope at hand right now, but I do have a laptop and some spare time to play around with it.
voltsandjolts:
This has been done several times in the past for older Rigol models.
Maybe the HDO1000 wfm format is compatible with one of those implementations already, dunno.
e.g.
https://github.com/scottprahl/RigolWFM

This was quite a good utility for the 1052E, with good window options for fft:

Rigol seem uninterested in fft features such as averaging or peakhold, so a PC app is likely gonna be the only way to get those nice features. But it's a slower and clunkier than having it built-in of course. Hello..Rigol..are you listening.............<crickets>
